Minecarts face always face west after rail is broken

I was playing around in creative mode and noticed that Minecarts placed facing east would flip when the rail under them was broken. Intrigued, I tested what they would do when facing north. They flipped west. I could only notice this because I used a Minecart Furnace and a Minecart Chest.

Something else interesting about the Minecart Chest is that the front of the chest appears to face backwards from the entity's actual position. I don't know if this is intentional or not.

I'm quite sure that this is present in every version since at least 1.12.2, since it does it in that version as well.
